Thank you very much for your detailed report! I have one SanDisk card which sometimes fails to probe on one specific board, so for me it was really hard to debug the issue because it was hardly reproducible. Can you tell me which cards fail and if they do that realiably? Also which Renesas HW do you use? So much for a first response. I will have a closer look at your findings tomorrow.
